[package] uhttpd:
- fix parsing of interpreter entries in the config file, fixes serving of static files as .cgi with X-Wrt - better cope with connection aborts, especially during header transfer - fix return value checking of TLS reads and writes, solves some blocking issues git-svn-id: svn://svn.openwrt.org/openwrt/trunk@22692 3c298f89-4303-0410-b956-a3cf2f4a3e73
